Combustion | Science 101

Carbon-hydrogen bonds store potential energy. When the kindling reaches a high enough temperature, these bonds break, releasing the stored energy as light and heat. During combustion, oxygen reacts with the broken-down hydrocarbons, forming new molecules like carbon dioxide (CO2) and water (H2O). This reaction releases even more energy, sustaining the fire. It's a self-perpetuating cycle - fuel breaks down, reacts with oxygen, and releases energy to break down even more fuel.
